Debian DSA-174-1 : heartbeat - buffer overflow

critical Nessus Plugin ID 15011

Synopsis

The remote Debian host is missing a security-related update.

Description

Nathan Wallwork discovered a buffer overflow in heartbeat, a subsystem for High-Availability Linux. A remote attacker could send a specially crafted UDP packet that overflows a buffer, leaving heartbeat to execute arbitrary code as root.

Solution

Upgrade the heartbeat package immediately if you run internet connected servers that are heartbeat-monitored.

This problem has been fixed in version 0.4.9.0l-7.2 for the current stable distribution (woody) and version 0.4.9.2-1 for the unstable distribution (sid). The old stable distribution (potato) doesn't contain a heartbeat package.
